如何将byte []反序列化为在方法调用时强制转换的泛型对象

Question

我正在开发一个对象加密类.我已经解决了所有问题,但我希望能够使用一个反序列化方法加密/解密任何对象类型.截至目前,阻止我的唯一方法是反序列化方法.我有函数返回类型(对象)希望返回弱类型对象.只要我在返回值赋值期间转换类型,它就可以工作,但是如果我反序列化为类型'object',结果就是byte [].

这意味着我必须为我想要操作的每个对象(T)编写反序列化方法.我想要做的是将Type(T)作为参数传递给deserialize方法,这样我就可以反序列化为object(T),然后返回类型化的对象.

问题是显然不允许使用类型化参数.
如果我这样做,obj = (type.GetType())br.Deserialize(ms); 我会; expected介于'(object(T))和br.之间.

如果obj = (br.Deserialize(ms) as type);我得到了The type of namespace "type" could not be found. (are you missing a using directive or an assembly reference?)

或者我得到一个无法解决的符号错误.任何帮助表示赞赏.完整代码如下.

        private byte[] serialize(object param)
    {
        byte[] encMsg = null;
        using (MemoryStream ms = new MemoryStream())
        {
            IFormatter br = new BinaryFormatter();
            br.Serialize(ms, param);
            encMsg = ms.ToArray();
        }

        return encMsg;
    }

    private object deserialize(byte[] param)
    {
        object obj = null;
        using (MemoryStream ms = new MemoryStream(param))
        {
            IFormatter br = new BinaryFormatter();
            obj = (br.Deserialize(ms) as myObject);
        }

        return obj;
    }

    private byte[] encrypt(byte[] param)
    {
        byte[] encMsg = null;
        using (Aes myAes = Aes.Create())
        {
            myAes.Padding = PaddingMode.ANSIX923;
            ICryptoTransform autoBot = myAes.CreateEncryptor(myAes.Key, myAes.IV);
            using (MemoryStream ms = new MemoryStream())
            {
                using (CryptoStream cs = new CryptoStream(ms, autoBot, CryptoStreamMode.Write))
                {
                    cs.Write(param, 0, (int)param.Length);
                }
                encMsg = ms.ToArray();
            }
        }
        return encMsg;
    }

    private byte[] decrypt(byte[] key, byte[] iv, byte[] param)
    {
        byte[] dcparam = null;
        using (Aes myAes = Aes.Create())
        {
            myAes.Padding = PaddingMode.ANSIX923;
            ICryptoTransform autoBot = myAes.CreateDecryptor(key, iv);
            using (MemoryStream ms = new MemoryStream())
            {
                using (CryptoStream cs = new CryptoStream(ms, autoBot, CryptoStreamMode.Write))
                {
                    cs.Write(param, 0, (int)param.Length);
                }
                dcparam = ms.ToArray();
            }
        }
        return dcparam;
    }

Answer 1

您要反序列化的类型必须在编译时知道.所以您的方法可以是:

private T Deserialize<T>(byte[] param)
{
    using (MemoryStream ms = new MemoryStream(param))
    {
        IFormatter br = new BinaryFormatter();
        return (T)br.Deserialize(ms);
    }
}

现在你可以像使用它一样

var myclass = Deserialize<MyClass>(buf);
